Is RYR2 p.Ser528Phe (c.1583C>T) pathogenic?

RYR2 p.Ser528Phe (c.1583C>T) is classified Uncertain significance in RYR2 (ClinVar, Multiple submitters, 4 submitters; last evaluated 2025-11-28). AlphaMissense: likely benign (0.1424); Very rare (popmax 0.00133%, afr); Associated with catecholaminergic polymorphic ventricular tachycardia 1.

What condition is associated with RYR2 p.Ser528Phe (c.1583C>T)?

RYR2 p.Ser528Phe (c.1583C>T) is associated with catecholaminergic polymorphic ventricular tachycardia 1, cardiomyopathy, catecholaminergic polymorphic ventricular tachycardia (ClinVar).

How common is RYR2 p.Ser528Phe (c.1583C>T) in the general population?

RYR2 p.Ser528Phe (c.1583C>T) is very rare (popmax 0.00133%, afr) (gnomAD).

What do computational predictors say about RYR2 p.Ser528Phe (c.1583C>T)?

AlphaMissense predicts likely benign (score 0.1424) — an in-silico prediction, not a clinical call.

RYR2 p.Ser528Phe

Q: How is Inherited isolated arrhythmogenic cardiomyopathy inherited?

Typically Autosomal dominant (Orphanet). A genetic counselor can assess individual risk for a family.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
